We had the need to notify the assigned user when an email was received that was related to a Case record. To make our application more flexible we extended this concept to be reusable for email received that was related to any module. We then further broke out the notification functions to be reusable in other scenarios.
Here is a guest post from Sugar Developer Francesca Shiekh who works for our customer Wolfram Research. She also happens to be one of the most active developers in the Sugar Developer Community! In this post, Francesca and Wolfram Research Systems Administrator Trey Mitchell share how you can customize Sugar to use an alternative PDF generator for the creation of PDF documents in Sugar.
Creating better PDFs with CSS
We wanted a custom Contracts module that allowed specific styling to be applied to all Contract PDFs. We determined that we could use CSS to apply a consistent style to any and all PDF documents associated with this new custom Contracts module. But we could not achieve this with SugarPDF due to the complexity of our CSS. Also overriding sugarpdf.pfdmanager.php was not an option as it is an extension of TCPDF and TCPDF has limited CSS support.
It was therefore necessary for use to look at alternatives that could better handle CSS. We found a promising open source tool called wkhtmltopdf that uses WebKit. WebKit should be familiar because it is the same layout engine used in Safari and Google Chrome, and is therefore very accurate in rendering CSS.
We still wanted to leverage the PDF Manager module to create and maintain our PDFs. We planned to develop our Contract templates in HTML with our own custom CSS and then copy them into the HTML editor that was already available in PDF Manager.
